ARIES-ST is a 1000 MW fusion power plant conceptual design based on a low aspect ratio ‘spherical torus’ (ST) plasma. The plasma-facing components include the inboard and outboard first wall, divertor plates, and plasma stability plates. Several unique aspects of ST plasma influence the engineering design. The limited inboard space precludes a full inboard divertor slot, such that substantial p...

Twinning-induced plasticity (TWIP) steel is a second-generation advanced high strength grade developed for automotive applications. TWIP steels exhibit an excellent combination of and ductility, mainly originating from the activation deformation twinning. However, generally relatively low yield (YS), which limits their practical Thus, developing YS without ductility loss essential to increase i...

In order to better understand the thermomechanical behavior of the skin and its direct environment, we present an experimental study using infrared thermography. This experimental study aims to highlight quantitatively some effects of blood flow on the heat diffusion. The originality of this research is to change the blood flow by using effects of gravity and to quantify the temperature changes...

We analyze three-dimensional finite coupled thermomechanical deformations of a rectangular plate with two parallel notches placed symmetrically about the horizontal centroidal plane of the plate. The edge surface of the plate between the two notches is struck by a cylindrical projectile of diameter equal to the distance between the notches and made of the same material as the plate. The plate m...

In the present study, a three-dimensional finite element model has been developed to simulate the temperature, stress and deformation fields in continuous wave (CW) laser micro-welding of thin stainless steel sheet. The welding deformation was experimentally evaluated using a single-mode fiber laser with a high-speed scanning system. Application of developed thermal model demonstrated that the ...

Abstract Austenitic Cr–Ni stainless-type 301LN steel was subjected to a double-reversion annealing (DRA) treatment develop bulk grain-refined microstructures. The tensile properties and formability of the DRA structures were determined by high-speed Erichsen cupping tests at strain rate 1.5 s ?1 (50 mm ) compared with those coarse-grained steel. Detailed microstructural features characterized u...

Purpose: To provide a preliminary evaluation of health outcomes for a type of thermomechanical massage device used in Asia, Middle East, and Europe and now in the United States. The device under study is manufactured by Migun Medical Instruments International (Taejeon, Korea) and has an estimated usage of 24-35 million client-sessions per year worldwide. Methods: findings were obtained from unp...

BASED ON THE FIELD EQUATION for the number density of voids and the expression for the expansion of a spherical void in a perfectly plastic infinite body subjected to a uniform hydrostatic tensile stress, an expression for the rate of dilatation of voids is derived. Damage is defined as the volume density of voids. The flow stress of the material is assumed to decrease affinely with an increase...
